1OVERVIEW
HGM9600 series genset controllers are used for genset automation and monitor control system of
single unit to achieve automatic start/stop, data measure, alarm protection and “three remote” (remote
control, remote measuring and remote communication). The controller adopts large liquid crystal
display (LCD) and selectable Chinese, English or other languages interface with easy and reliable
operation.
HGM9600 controller adopts 32-bit micro-processor technology with precision parameters measuring,
fixed value adjustment, time setting and threshold adjusting and etc. The majority of parameters can
be set using front panel and all the parameters can be set using PC (via USB port) and can be adjusted
and monitored with the help of RS485 and ETHERNET ports. Controllers are fitted with Micro SD for
real-time operation data recording for convenient browsing and timely fault detection. It can be widely
used in a number of automatic genset control system with compact structure, simple connections and
high reliability.

5.4 AUTO START/STOP OPERATION
Press , its indicator lights, and controller enters Auto mode.
Starting Sequence,
1. HGM9620: When mains power is abnormal (over and under voltage, over and under frequency, loss of
phase, phase sequence wrong), it enters mains “abnormal delay” and LCD display count down time.
When mains abnormal delay is over, it enters into “start delay”; it also enters this mode when “remote
start on load” is active.
2. HGM9610: Generator enters “start delay” as soon as “remote start on load” is active.
3. Start Delay timer is shown on Status page of LCD.
4. When start delay is over, preheat relay outputs (if this be configured), “preheat start
delay XX s” is shown at the bottom line of LCD.
5. When preheat delay is over, fuel relay outputs 1s and then start relay output; if engine crank fails

HGM9600 Series Genset Controller User Manual Page 20 of 73
during “cranking time”, the fuel relay and start relay deactivated and enter “crank rest time” to wait for
next crank.
6. If engine crank fails within setting times, the controller sends Fail to Start signal and Fail to Start
message appears on LCD alarm page.
7. In case of successful crank attempt, “safety on timer” starts. During this period, low oil pressure, high
water temperature, under speed, charge failure alarms are disabled. As soon as this delay is over,
“start idle delay” is initiated (if configured).
8. During “start idle delay”, under speed, under frequency, under voltage alarms are inhibited. When this
delay is over, “warming up delay” starts (if configured).
9. When “warming up delay” is over, if generator state is normal, its indicator will be illuminated. If
voltage and frequency has reached on-load requirements, the closing relay will be energized,
generator will accept load, generator power indicator will turn on, and generator will enter Normal
Running state; if voltage and frequency are abnormal, the controller will initiate alarm (alarm type will
be displayed on LCD alarm page).
NOTE: In case of “Remote Start (off Load)”, the procedure is the same, except for step NO. 9: the closing relay will NOT
be energized, generator will NOT accept load.
Stopping Sequence:
1. HGM9620: When mains return normal during gen-set running, it enters mains voltage “normal delay”.
When mains normal delay is over, enter “stop delay”; also can be into this mode when “remote start on
load” is inactive.
2. HGM9610: Generator enters “stop delay” as soon as “remote start on load” is inactive.
3. When stop delay is over, close generator relay is un-energized; generator enters into “cooling down
time”. After “transfer rest time”, close mains relay is energized. Generator indicator extinguish while
mains indicator lights.
4. Idle relay is energized as soon as entering “stop idle delay”.
5. If enter “ETS hold delay”, ETS relay is energized. Fuel relay is deactivated and decides whether
generator is stopped or not automatically.
6. Then enter gen-set “Fail to stop time”, auto decides whether generator is stopped or not
automatically.
7. Enter “after stop time” (if configured) as soon as generator stops. Otherwise, controller will send “Fail
to Stop” alarm. (If gen-set stopped successfully after warning of “Fail to Stop”, it will enter “after stop
time” and remove alarm)
8. Enter “generator at rest” as soon as “after stop time” is over.
